Abstract

The method involves calculating perimeter length of a first longitudinal profile (51), and determining spatial coordinates of points (P1, P2) of a second longitudinal profile obtained from projection of the first profile or a third longitudinal profile (50) on a curved surface derived from a shape parameter of an ophthalmic lens. The spatial coordinates of the points are corrected so as to equalize perimeter length of the second longitudinal profile with the perimeter length of the first longitudinal profile. Machining setpoint is deduced from the corrected spatial coordinates.
